As for tyranny, I agree with Plato - the best leaders are those who don't want to be a leader but are forced into the position
Those who willingly want to be a leader always run the risk of becoming corrupt no matter how "good" and "pure" they were before. And naturally become arrogant, think they know what's best, and may become tyrannical doing what's "best"
The only problem is, leaders who are put into their position not because they wanted the power may resent their subjects, and abuse them and their power bc - "I don't want this position", see their responsibility and subjects as a "burden" and also the "if I have to suffer, you will too" mindset, rather than "bc I suffered I will make sure no one else will in the same way" mindset
This is similar to TW for child abuse so I'll put the rest in a spoiler mothers who abuse their children bc they were unplanned as they view them as a burden, mothers who abuse their children bc they are disabled, and view them as a burden and in the way of getting a "normal" life, same with fathers who didn't want their children and abuse them becuase, and parents who k*ll their children
So if a leader is put into that position because other people think they would be a good leader and not because they want the position, they don't - and they don't resent their subjects because of the burdern, that would be the best leader
A leader truly chosen by the people, not one that wants power, runs for a position, campaigns, and then is chosen, but purely chosen bc other people because of leadership qualities alone, and not because they are "an option". So politicians I don't ever think could be the best possible leader
Which is why some monarchs who didn't want the position or to be royalty but cared about their people, and tried to relate with and understand and listen to the common people have been fairer and "better" rulers than presidents, even though they were elected
NOT the monarchs who saw themselves as above their subjects because of being born into that position and being royalty
Ofc that being said, I am not at all advocating for monarchy or saying I want it, the system of birth determing who rules is unfair and ridiculous
There will never really be a perfect system
